[0032] In the description of the present utility model, unless otherwise clearly defined, terms such as "arrangement", "installation", "connection", etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present utility model in combination with the specific content of the technical solution.

[0033] Figure 1 and Figure 2 Fig. shows the state of the bathroom heater 100 after being installed on the ceiling. The ceiling includes multiple horizontal keels 201 and multiple vertical keels 201. The horizontal keels 201 and the vertical keels 201 intersect and are perpendicular to each other. Only two parallel keels 201 are shown in the drawing, and these two keels 201 can be regarded as two vertical keels 201 or two horizontal keels 201. The ceiling further includes multiple ceiling panels 202, and the ceiling panels 202 are connected to the keels 201. For example, as Figure 10 shown, the ceiling panel 202 includes a flanging 204, the bottom of the keel 201 clamps the flanging 204, and the flanging 204 of the ceiling panel 202 is clamped by the keel 201, thereby realizing the fixation between the ceiling panel 202 and the keel 201.

[0034] As Figure 1 shown, the bathroom heater 100 includes a main unit 101, an air outlet panel assembly 107, an air outlet pipe 104, and a support frame 106. The air outlet panel assembly 107 is arranged outside the main unit 101, the air outlet panel assembly 107 is separately arranged from the main unit 101, and both ends of the air outlet pipe 104 are connected to the main unit 101 and the air outlet panel assembly 107 respectively. The air outlet panel assembly 107 is provided with an air outlet 108, the main unit 101 is provided with an air inlet 109, both the air outlet 108 and the air inlet 109 are exposed at the bottom of the ceiling (as Figure 2 shown), and both the air outlet 108 and the air inlet 109 are arranged in the bathroom. The main unit 101 is used to convey air to the air outlet 108 through the air outlet pipe 104. The heated air will enter the bathroom through the air outlet 108, thereby creating a warm and comfortable environment for the users in the bathroom. The air can be heated by the main unit 101 or by the air outlet panel assembly 107 (specific introduction will be made below). As Figure 3As shown, the support frame 106 is spanned above the ceiling 202, and the support frame 106 is spaced from the ceiling 202. The support frame 106 is connected to the air outlet panel assembly 107, and the support frame 106 is also connected to the keel 201. At least a part of the gravity of the air outlet panel assembly 107 directly acts on the support frame 106, and moreover, the gravity of the air outlet panel assembly 107 can be transmitted to the keel 201 through the support frame 106, so that the keel 201 and the support frame 106 jointly support the air outlet panel assembly 107. In this way, the gravity of the air outlet panel assembly 107 mainly acts on the support frame 106 and the keel 201, and the part of the gravity of the air outlet panel assembly 107 directly acting on the ceiling 202 is less, which is beneficial to reducing the risk of deformation and falling of the ceiling 202.

[0035] In order to improve the supporting effect of the support frame 106 on the air outlet panel assembly 107, the support frame 106 can be made of a metal with better strength such as steel or aluminum alloy. In order to improve the stability of the air outlet panel assembly 107, the support frame 106 can be provided with two (as Figure 3 or Figure 4 shown), and the two support frames 106 are spaced along the length direction of the keel 201.

[0036] In some embodiments, the air outlet panel assembly 107 can also be connected to the ceiling 202. For example, as Figure 3 shown, the ceiling 202 is provided with mounting holes 203, and screws (not shown) pass through the mounting holes 203 and are connected to the air outlet panel assembly 107. In this setting mode, the ceiling 202 and the keel 201 jointly support the air outlet panel assembly 107. It should be noted that in the prior art, the gravity of the air outlet panel assembly 107 is basically borne by the ceiling 202. And in the above setting mode, a part of the gravity of the air outlet panel assembly 107 will directly act on the ceiling 202, however, the gravity of the air outlet panel assembly 107 is jointly borne by the ceiling 202 and the keel 201, and the gravity of the air outlet panel assembly 107 borne by the ceiling 202 is less. (Compared with the prior art), therefore, the risk of deformation and falling of the ceiling 202 is lower.

[0037] The following specifically introduces the cooperation relationship between the support frame 106 and the keel 201, and the cooperation relationship between the support frame 106 and the air outlet panel assembly 107.

[0038] As Figure 5As shown, the support frame 106 includes a support portion 117 and two first limiting portions 120. The support portion 117 includes a first connection surface 118, and the first connection surface 118 is arranged downward and is used for connecting with the top surface of the keel 201. In this embodiment, the first connection surface 118 is the bottom surface of the support portion 117, and the first connection surface 118 abuts against the top surface of the keel 201; in some other embodiments, the first connection surface 118 and the top surface of the keel 201 can also be connected by screws. Each first connection surface 118 is connected to a first limiting portion 120, and the two first limiting portions 120 are arranged at intervals in the horizontal direction, and the first limiting portion 120 protrudes downward relative to the first connection surface 118. Please refer to Figure 5 and Figure 7 , for the two keels 201 connected to the support frame 106, each keel 201 is connected to a first connection surface 118, the two keels 201 are arranged between the two first limiting portions 120, and the first limiting portion 120 is located at the side of the keel 201. During the installation process of the bathroom heater 100, the user can slide the support frame 106 along one end of the keel 201 to a preset installation position, and the first limiting portion 120 can be used to limit the movement of the support frame 106 in the width direction of the keel 201 (which can correspond to Figure 3 the front-back direction), so as to install the support frame 106 and prevent the deviation distance of the support frame 106 from being too large.

[0039] As Figure 5 shown, the top surface of the support portion 117 is a second connection surface 119, and the second connection surface 119 is connected to the air outlet panel assembly 107. For example, in some embodiments not shown, the second connection surface 119 and the air outlet panel assembly 107 can be fixed by screws. Another example is that in the embodiment shown in Figure 7 , the air outlet panel assembly 107 includes a connection plate 112, the bottom surface of the connection plate 112 abuts against the second connection surface 119, and the second connection surface 119 directly supports the air outlet panel assembly 107; in this way, the assembly process of the support frame 106 and the air outlet panel assembly 107 does not require the operation of screwing, which is beneficial to improving the installation convenience of the bathroom heater 100.

[0040] As Figure 5 shown, the support portion 117 arches upward relative to the connection line of the two first limiting portions 120, thereby forming a downward notch 122, and a part of the air outlet panel assembly 107 passes through the notch 122 (as shown in Figure 7As shown in the figure). In this setting, the support portion 117 is arched, and the support portion 117 has strong load-bearing capacity. The support portion 117 can stably support the air outlet panel assembly 107. Moreover, since the support portion 117 is arched, the pressure exerted by the connecting plate 112 of the air outlet panel assembly 107 on the support portion 117 can be well dispersed to the keel 201, and the keel 201 and the support portion 117 can jointly and stably support the air outlet panel assembly 107. In addition, since the air outlet panel assembly 107 is inserted through the notch 122, the structural compactness of the bathroom heater 100 is relatively high, and the space occupied by the bathroom heater 100 is small.

[0041] As Figure 5 and Figure 6 shown, the support frame 106 further includes a second limiting portion 121. The second limiting portion 121 is connected to the second connecting surface 119, and the second limiting portion 121 protrudes upward relative to the second connecting surface 119. As Figure 8 shown, the connecting plate 112 is provided with a limiting hole 125, and the second limiting portion 121 is inserted through the limiting hole 125. On the one hand, the cooperation between the second limiting portion 121 and the limiting hole 125 can realize the positioning when the support frame 106 and the air outlet panel assembly 107 are assembled with each other, improving the installation convenience of the bathroom heater 100. On the other hand, the hole wall of the limiting hole 125 can limit the horizontal movement of the second limiting portion 121, thereby reducing the risk of the air outlet panel assembly 107 and the support frame 106 separating from each other.

[0042] As Figure 8 shown, in some embodiments, the second limiting portion 121 is in the shape of a barb, and the second limiting portion 121 includes a longitudinal body 123 and a transverse body 124. The bottom end of the longitudinal body 123 is connected to the second connecting surface 119. The longitudinal body 123 is inserted through the limiting hole 125, and the top end of the longitudinal body 123 is located above the connecting plate 112. The transverse body 124 is connected to the top end of the longitudinal body 123. The transverse body 124 protrudes in the horizontal direction relative to the longitudinal body 123, and the projection of the transverse body 124 from top to bottom can fall on the top surface of the connecting plate 112. In the above setting, the transverse body 124 can limit the upward movement of the air outlet panel assembly 107 to prevent the air outlet panel assembly 107 from separating from the support frame 106. The following explains "the projection of the transverse body 124 from top to bottom can fall on the top surface of the connecting plate 112". Taking Figure 8For example, the transverse body 124 protrudes leftward relative to the longitudinal body 123, and a part of the transverse body 124 is located on the left side of the limiting hole 125, so that the projection of the transverse body 124 from top to bottom can fall on the top surface of the connecting plate 112. The transverse body 124 is arranged above the connecting plate 112 at intervals. After the connecting plate 112 moves upward a certain distance relative to the second limiting part 121, the transverse body 124 will block the connecting plate 112 to prevent the second limiting part 121 from completely disengaging from the limiting hole 125, thereby preventing the air outlet panel assembly 107 from separating from the support frame 106. It should be noted that in order to enable the second limiting part 121 to pass through the limiting hole 125 from bottom to top (mainly occurring during the installation of the bathroom heater 100), the width L of the transverse body 124 1 is not greater than the width L of the limiting hole 125 2 .

[0043] As Figure 10 shown, in some embodiments, the air outlet panel assembly 107 includes a housing 133 and a heater 115. The housing 133 is provided with an air outlet 108 and a connection port 113, and the connection port 113 is connected to the air outlet pipe 104. The heater 115 is located inside the housing 133, and the heater 115 is located between the connection port 113 and the air outlet 108. Figure 10 The dotted line with an arrow indicates the flow path of the air when it flows through the air outlet panel assembly 107. The heater 115 is used to heat the air flowing through the heater 115, so that the warm air is blown out from the air outlet 108.

[0044] Since the heater 115 is integrated in the air outlet panel assembly 107, the heater 115 may not be provided in the main unit 101. The air flowing in the air outlet duct 104 is the air that has not been heated by the bathroom heater 100, and the temperature of the air flowing in the air outlet duct 104 is relatively low. In this way, the air in the air outlet duct 104 will not significantly heat the air outlet duct 104. During the operation of the bathroom heater 100, the temperature of the air outlet duct 104 is relatively low, and the air outlet duct 104 is not easily deformed due to high temperature. The risk of damage and air leakage of the air outlet duct 104 due to deformation is relatively low. Moreover, since the temperature of the air outlet duct 104 is relatively low, the air outlet duct 104 will not transfer a large amount of heat to the keel 201, ceiling 202, electric wires or other electrical appliances (such as lamps) around the air outlet duct 104, which is beneficial to reducing the risk of damage to the keel 201, ceiling 202, electric wires or other electrical appliances around the air outlet duct 104 and improving their service life. In addition, since the air is heated in the air outlet panel assembly 107, the heated air will subsequently flow out of the air outlet 108 quickly and enter the bathroom. During the process of heating the air until it flows out of the air outlet 108, the flow path and flow time of the air in the bathroom heater 100 are relatively short, and less heat of the air is dissipated to the suspended ceiling, which is beneficial to reducing heat loss and improving the energy efficiency of the bathroom heater 100. Although the air outlet panel assembly 107 is integrated with the heater 115, in this application, the air outlet panel assembly 107 is supported by the support frame 106 and the keel 201 together, reducing the impact of the overall gravity of the air outlet panel assembly 107 on the ceiling 202, and the ceiling 202 is not easily deformed due to the weight of the added heater 115.

[0045] As Figure 10 shown, in some embodiments, the housing 133 includes a main body 111 and a connector 110. The air outlet 108 is disposed on the outer surface of the main body 111. For example, the air outlet 108 is disposed on the bottom surface of the main body 111. The connection port 113 is disposed on the outer surface of the connector 110. The connector 110 is detachably connected to the main body 111. For example, the connector 110 and the main body 111 can be connected by means of snap connection, socket connection, etc. The main body 111 includes a first grille portion 114, and the connector 110 includes a second grille portion 116. The first grille portion 114 and the second grille portion 116 jointly clamp the heater 115, thereby fixing the heater 115 inside the housing 133. The first grille portion 114 and the second grille portion 116 can be made of heat-resistant materials to prevent the first grille portion 114 and the second grille portion 116 from being severely deformed at high temperatures. It should be noted that in Figure 10 it, a baffle 132 is further provided at the air outlet 108, Figure 10 as shown in the figure, the bathroom heater 100 shown is in the shutdown state, and at this time the baffle 132 blocks the air outlet 108; after starting up and running, the baffle 132 will rotate and release the blockage of the air outlet 108 (the motor for driving the rotation of the baffle 132 is not shown) so that the air can flow out.

[0046] In some other embodiments, the heater 115 may not be integrated in the air outlet panel assembly 107 either. For example, as Figure 11 shown, the air outlet duct 104 includes an inner duct 135 and an outer duct 136, and the outer duct 136 is sleeved outside the inner duct 135. The lumen of the inner duct 135 is the inner air duct 137, and the inner wall surface of the outer duct 136 and the outer wall surface of the inner duct 135 are spaced apart to form an outer air duct 138. The heater 115 is installed at the inlet end 105 of the inner air duct 137. The main unit 101 conveys air to the air outlet panel assembly 107 through the inner air duct 137 and the outer air duct 138. Specifically, both the inner air duct 137 and the outer air duct 138 communicate with the first chamber 130 of the main unit 101 (the internal structure of the main unit 101 and the first chamber 130 can be referred to below). A part of the air leaving the main unit 101 from the first chamber 130 enters the inner air duct 137, and the other part enters the outer air duct 138. These two parts of air will eventually converge in the air outlet panel assembly 107. Since the heater 115 is installed at the inlet end 105 of the inner air duct 137 instead of being provided in the outer air duct 138, the air entering the inner air duct 137 will be heated by the heater 115, and the temperature of the air flowing in the inner air duct 137 is relatively high. The heat of the air flowing in the inner air duct 137 will be transferred to the outer wall surface of the inner duct 135. Therefore, the air flowing in the outer air duct 138 will also be heated, and the heat dissipated by the inner duct 135 can be fully utilized, and the inner duct 135 is not likely to overheat and deform or be damaged. Compared with the air flowing in the inner air duct 137, the temperature of the air flowing in the outer air duct 138 is relatively low. Correspondingly, the temperature of the outer wall surface of the outer duct 136 is relatively low, and less heat is dissipated from the outer wall surface of the outer duct 136. Therefore, Figure 11 the embodiment shown can also reduce the risk of damage to the keel 201, the ceiling 202, wires or other electrical appliances around the upstream pipe section of the air outlet duct 104, as well as reduce heat loss and improve the energy efficiency of the ceiling-mounted bathroom heater 100.

[0047] Next, the structure of the main unit 101 will be introduced. As Figure 9 shown, the main unit 101 includes a main unit housing 126, a fresh air fan 131 and an exhaust fan 128. To facilitate showing the internal structure of the main unit 101, Figure 9A part of the main housing 126 is omitted. A first chamber 130 and a second chamber 127 are provided inside the main housing 126. The fresh air fan 131 is disposed in the first chamber 130, and the exhaust air fan 128 is disposed in the second chamber 127. The bathroom heater 100 further includes a fresh air duct 102 and an exhaust air duct 103. The fresh air duct 102 and the exhaust air duct 103 are both connected to the main housing 126, and the lumen of the fresh air duct 102 and the lumen of the air outlet duct 104 communicate with the first chamber 130, and the lumen of the exhaust air duct 103 communicates with the second chamber 127. An air inlet 109 is provided on the outer surface of the main housing 126. For example, the air inlet 109 is located at the bottom of the main housing 126. The main housing 126 is connected to the keel 201 by screws, and the air inlet 109 is exposed in the bathroom. One end of the fresh air duct 102 away from the main housing 126 and one end of the exhaust air duct 103 away from the main housing 126 can both be disposed in the outdoor environment. When the fresh air fan 131 operates, the fresh air fan 131 can drive fresh air (outdoor air) to enter the first chamber 130 through the fresh air duct 102, and drive the air in the first chamber 130 to flow through the air outlet duct 104 to the air outlet 108. When the exhaust air fan 128 operates, the exhaust air fan 128 can drive the indoor air to enter the second chamber 127 from the air inlet 109, and drive at least a part of the air in the second chamber 127 to be discharged to the outdoor environment through the exhaust air duct 103. As described above, in some embodiments, the main unit 101 may not be provided with the heater 115, and the air outlet panel assembly 107 is provided with the heater 115 or the heater 115 is provided at the inlet end 105 of the inner air duct 137; if the main unit 101 is provided with the heater 115, the heater 115 may be provided in the first chamber 130.

[0048] As Figure 9As shown, in some embodiments, the host 101 further includes a valve 134, which is installed on the host housing 126. When the valve 134 is in the open state, the first chamber 130 and the second chamber 127 communicate with each other; when the valve 134 is in the closed state, the first chamber 130 and the second chamber 127 are separated from each other. The host housing 126 includes a partition 129, which is arranged between the first chamber 130 and the second chamber 127. One side surface of the partition 129 serves as the wall surface of the first chamber 130, and the other side surface of the partition 129 serves as the wall surface of the second chamber 127. The valve 134 can be installed on the partition 129. The valve 134 includes a motor and a rotatable valve plate (not shown). The partition 129 is provided with a through hole (not shown), and the valve plate is arranged at the through hole. The valve plate can rotate relative to the partition 129 under the drive of the motor, so as to change the angle of the valve plate relative to the through hole. When the valve 134 is in the closed state, the valve plate completely covers and blocks the through hole; when the valve 134 is in the open state, a gap is formed between the valve plate and the hole wall of the through hole, and air can pass through the gap. In other embodiments, the movement mode of the valve plate can also be set to move, and the drive mechanism for driving the valve plate to move can be set as a linear motor, a lead screw module, an electromagnet, etc.

[0049] In the case where the valve 134 is provided, the functions or modes of the bathroom heater 100 are more, the situations that the bathroom heater 100 can apply to are more, and the use experience of the bathroom heater 100 is better. In the case where the valve 134 is provided, the air that is heated and finally flows out from the air outlet 108 can include the following two situations: (1) the air flowing out from the air outlet 108 is fresh air; (2) the air flowing out from the air outlet 108 is return air.

[0050] For the above-mentioned first situation, the bathroom heater 100 is in the fresh air mode, and the operation mode of the bathroom heater 100 is: the valve 134 is in the closed state, and the fresh air fan 131, the exhaust fan 128 and the heater 115 are all turned on. At this time, the operation of the exhaust fan 128 is mainly to ensure the air pressure balance in the bathroom. The return air entering the host 101 under the drive of the exhaust fan 128 does not enter the first chamber 130, and all the air flowing out from the air outlet 108 is fresh air.

[0051] For the above-mentioned second situation, the bathroom heater 100 is in the full return air mode, and the operation mode of the bathroom heater 100 is: the valve 134 is in the open state, the fresh air fan 131 is turned off, and the exhaust fan 128 and the heater 115 are turned on. At this time, the movement path of the air is: bathroom → air inlet 109 → second chamber 127 → exhaust fan 128 → valve 134 → first chamber 130 → air outlet pipe 104 → air outlet 108 → bathroom. At this time, all the air flowing out from the air outlet 108 is return air.

[0052] Generally speaking, the temperature of the return air is lower than that of the fresh air (especially in cold weather conditions), and the fresh air is drier than the return air. The all-fresh air mode can provide relatively dry and fresh air for the bathroom to relieve the stuffy feeling in the bathroom. Compared with the all-fresh air mode, the all-return air mode requires less heating, and the bathroom can be quickly heated through the all-return air mode.

[0053] In some embodiments, the bathroom heater 100 may further have a ventilation mode. In the ventilation mode, the fresh air fan 131 does not operate, the exhaust fan 128 operates, and the valve 134 is in a closed state. In the ventilation mode, the bathroom heater 100 is equivalent to an exhaust fan. Indoor air enters the second chamber 127 from the air inlet 109 and then flows out to the outdoor environment through the exhaust pipe. The ventilation mode is applicable to the situation where the bathroom only needs ventilation and does not need heating.
